<p>A system for alternating additional battery drain from one of at least two battery packs (16, 18) by the use of a reversible electrical coupling means (32) where the battery packs (16, 18) are arranged in series and the coupling means includes two elements (34, 36) and each element (34, 36) has contact points to distribute the full voltage capacity to one equipment operation (12) and to also drain additional voltage from one of said battery packs (16, 18) to another equipment operation (14) simultaneously.</p> |
